I heard they do that on purpose though to discourage super technical builds and keep some mystery etc behind the systems. I find it refreshing in a way, where I focus less on the minute details and more about just playing the game. But I know it will annoy some like you mentioned.
Its fine to have "mystery" in the system and let players discover how things works by trial and error. However for this to happen, the game need to be solid and bug free. Unfortunately, people don't trust PB since some skills are buggy and/or misleading, not just in Elex and past games as well.
